Assist Control Ventilation(A/C)
Under A/C, mandatory ventilator breaths can be
triggered within a time window to synchronize them with
the patient's spontaneous breathing.
The ventilator rate is then higher than the rate set.
If spontaneous breathing does not occur, the ventilator
applies mandatory breaths at the set (minimum) rate.
● First set ventilation as for CMV, see page 30, then:

mode of ventilation.
Synchronized Intermittent Mandatory
Ventilation (SIMV)
SIMV is a combination of mandatory ventilation and spon-
taneous breathing. It enables the patient to breathe spon-
taneously in between mandatory ventilator breaths. If the
patient does not inspire spontaneously within a certain
time window, the ventilator will apply an unsynchronized
mandatory breath.
For low rates of mandatory ventilator breaths, the trigger
window should not be longer than 5 seconds in order to
guarantee a minimum expiratory time of 0.5 seconds. The
size of the trigger time window should be reduced with
increasing mandatory ventilator rates.
With synchronization, the mechanical ventilator breath is
applied during the preset time window to coincide with
the patient's inspiratory effort. The rate of the mechanical
ventilator breaths remains constant.
An asterisk (*) in the display indicates that synchroni-
zation is successful.
